Product overview
The F405 FC from Shenzhen Pakang Technology Co., Ltd. is a flight-controller component for drone builds, with Betaflight, INAV and ArduPilot firmware options. Its hardware combines an STM32F405RGT6 MCU, SPL06-001 barometer, ICM42688P gyro and AT7456E OSD chip, alongside a 16MB blackbox. The controller measures 36mm × 36mm, weighs 8g and uses a 30.5mm × 30.5mm mounting-hole pattern. These dimensions define its installation footprint, while six motor-output channels and four UART channels provide the specified control and peripheral connections.
Integration connections include Type-C USB and dedicated plugs for a receiver, analog camera, analog video transmitter, digital video transmitter and brushless ESC. Digital video support covers DJI, Vista and Caddx, with receiver protocols spanning ELRS, CRSF, S.BUS and the other listed options. Recommended component combinations extend from 5–7 inch freestyle builds to 8–9 inch higher-power builds. Those ESC, frame and motor combinations are matching recommendations, rather than stated package contents; the identified product is the flight controller, with LED-strip and buzzer support.
